The data stored on this mug has started to fade away badly. If this is what happens to the data I can see - what about all the data in the database? Worse again - no errors were thrown (I'm running in default mode)

Fearing the worst I migrated our corporate MongoDB instance to a etch-a-sketch stored in a vibration proof room.

I know I could have raised a bug about this or tried to get some support but a long blog post and a quick over-reaction is a more pragmatic approach. At the very least 10Gen could send me a new mug.
